JOURNAL AND OTHER BEARINGS.

"SPECIFICATION forming part 'of Letters Patent No. 269,636, dated December 26, 1882.

Application filed August 11, 1882.

To all whom it may concern:

Be it known that I, FERDINAND E. CANDA, of the city, county, and State of New York, have invented a new and useful Improvement in Journal and other Bearings, of which the following is a full, clear, and exact description.

This invention has forits object the production of an improved anti-friction bearing for journ als and other moving parts of machinery-- that is, a hearing by which the friction and wear of the moving parts in contact will be greatly reduced.

The invention consists in a bearing composed of a metallic compound or alloy in the form of an amalgam, with or without other substances held in mechanical combination, substantially as herein described.

To carry my invention into pracical effect I take any of the well-known metals or alloys used for forming bearings, and which will anialgamate with mercury-such as bronze or copper, tin, lead, and antimony-either separately or in the form of a metallic compound, and reduce the said metals or alloys to a powder in any suitable crushing and pulverizing mill. If the metals are separately pulverized, theyare then mixed together in any desired proportions. I then add to the pulverized metallic masses or mixtures about an equal amount of mercury--that is to say, to one hundred parts in weight to the pulverized inetallic mass or mixture 1 add about one huni dred parts of mercury. This is done in any amalgam, while in a plastic state, is then removed to a mold or molds of the required shape of the bearing to be produced, and pressure applied to give it form and to expel all superfluous (No specimens.)

J the same with the pulverized metals before the amalgamation takes-place, and subsequently subjecting the whole mass to pressure and allowing it to harden, as before described. Such graphite,although only mechanicallycombined 6a with the amalgam, will, by its well-known properties, give a selflubricatiugor greasy, soft, and smooth character to the bearings. Other lubricating substancessuch as micaor soapstonemight be mechanically combined with the amalgam in like manner.

By tempering the pressure applied to the amalgamated mass while in the molds the amount of mercury retained in the mass may be regulated as required.

Having thus described my inventiou,lclaini as new and desire to secure by Letters Patent- 1. A journal or other bearing composed of mercury and other suitable metals amalgamated therewith, substantially as specified.

2. Ajournal or other bearing composed of mercury and other suitable metals amalgamated therewith, and a lubricating; substance mechanically combined with the amalgam, es-. sentially as set forth.
